  • Patent number: 4000830
    Abstract: A lid for a cooking utensil wherein a substantially flat central section has a rim thereabout for engagement with the cooking utensil. Depending from the central section is a recessed plate characterized by a plurality of venting holes therein. A sliding cover is presented over the recessed plate for opening or closing the venting holes and may be totally removed therefrom for cleaning purposes. A further venting hole is presented about the rim periphery to vent the cooking utensil independently of the recessed plate. A dome-shaped cover may be incorporated to provide a steam or heat chamber above the lid by capturing steam escaping through the holes in the recessed plate. Venting holes may also be provided in the dome-shaped cover to provide for steam escapement so as to limit the moisture condensation within the cover.
